RAILWAY CAR AND TRAIN VENTILATION.

SPECIFICATION forming part of Letters Patent No. 626,389, dated June 6,1899.

Application filed May 27, 1898. Serial No. 681,948. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH MOCREERY, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in Railway Car and TrainVentilation; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to ventilating railway-cars, more particularlypassenger-cars; and it has for its object to so temper the atmosphere inthe cars that it shall be of the proper degree of temperature andmoisture.

The object of the in vention is accomplished by means of a device whichwill be hereinafter described.

Figure 1 represents in side elevation, partly in section, sufficient ofa passenger-train to illustrate the construction and use of theinvention. Fig. 2 represents aplan view, partly in section, of thedevice.

In the annexed drawings, the letter A represents a car, which may bepartly a baggagecar equipped with the apparatus. At one end a of the carA is placed a water-tank B, connected by apipe I) with a tank 0 underthe the car, an ordinary float-valve Z) controlling the flow of waterthrough the pipe Z). Within the car and adjacent to the tank 13 isplaced an air cleansing and cooling device D of any approvedconstruction containing the alternating baffle-plates (I and thewater-fender d, extending transversely of the air cleansing and coolingdevice. Near the top of the air cleansing and cooling device D there isan opening 01 to admit air into such air cleansing and cooling device.Arranged transversely of the air cleansing and cooling device at theair-inlet (Z is a perforated pipe c, with which communicates awater-pipe 6, connected with the pump E. To this pump E there leads awatersupply pipe 0 from the tank 0 under the car. Adjacent to the pump Eis a small engine F, and both the pump and engine may be operated bysteam from the locomotive through the pipes f, f, and f Located con-Veniently near the air cleansing and cooling device D is a blower G, soarranged that its intake is near the top of the water-fender cl.

1 This blower is run by the engine F. The ontlet or uptake 1 of thisblower G branches so as to communicate with the pipes H and H, therebeing a valve where the uptake communicates with the two pipes. Thesetwo pipes H H pass out through the top of the car and lie longitudinallyalong the middle of the top. At the outer end It 77, of these.

pipes is placed one half of a coupling 1, so that these pipes may beconnected with similar pipes upon the tops of adjacent ears. While Ihave devised a particular form of coupling for these pipes, only so muchneed be illustrated and described here as suits the purposes of thiscase. These couplings I are made of sufficiently flexible material toallow for the natural movement between cars, and the ends of the twoparts of each coupling are supported from the top of the car in such amanner as to keep the two parts of the coupling properly alined, so thatthey may catch when the cars are run together.

A car equipped as above described is intended to be used with a train ofpassengercars, each car having on its top a pipe similar to either ofthe pipes on the top of the apparatus-ear, except that in thepassengercar the pipe runs continuously from end to end, having ahalf-coupling at each end. At each end of the pipe K on top of thepassenger-car L there is connected a down-pipe M on each side of thecar, which communicates with a longitudinal pipe N, running along theside of the car at the bottom. At stated intervals these pipes N haveopenings, which may be regulated by valves in the usual manner. Thesepipes N may run alongside of or on top of the usual heater-pipes in thecar.

The pipes 11, H, and K have valves 721 721 717 at their ends, regulatedor controlled by handles which pass down into the car. These valves areopened or shut, according as it is desired to have air pass through thepipes or not.

In use air enters the air cooling and cleansing device D at theair-opening (1 At the same time water is withdrawn from the tank 0through the pipe 0 by the pump E and forced through the pipes e and eand passes out of the perforations of the pipe e as spray. The water andair commingling pass amid the battle-plates (1, being drawn through theair cooling and cleansing device by the force of the blower G. Onreaching the bottom the water is caught by the water-fender d and passesthrough the outlet-pipe (1 into the tank 0, While the air, which hasbeen moistened and tempered,passes through the blower G and is forcedinto the pipe H or H, according to the setting of the valve g. Theapparatus-car is provided with these two pipes, so that the air may beblown in either direction, rendering it unnecessary to reverse the car.The air is forced through the pipe H to the coupling I and into the pipeK, and passes down the pipes M into the pipes N and issues at theopening in the latter pipes into the car. Having described my invention,what I claim isv 1 1. A car provided with two water-tanks, on above theother and connected by a pipe, an air cleansing and cooling device, apump for forcing Water from the lowermost tank into such air cleansingand cooling device, a blower for withdrawing the air from the latter,and a pipe attached to the blower for distributing the air to the othercars of the train, as set forth.

2. The combination, in a car, of the tank, G, at the bottom, the aircleansing and cooling device, D, having air-inlets (1 at the top, and anoutlet at the bottom, the pump, E, and the pipes, c e e, for forcingwater from the tank, G, into the air cleansing and cooling device nearits top, the blower, G, having its intake at the opening in the bottomof the air cleansing and cooling device and having an outletand a pipefor distributing the air to the train connected at such outlet, and theengine for'operating such blower, as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH MOCREERY.
